Why Analyze for Trace Elements and Organic Compounds in Riverbed Sediments?
What Historical Trace Element and Organic Compound Data Are Available and How Can They Be Interpreted?
What Do the Historical Trace Element and Organic Compound Data Show?
What Do These Results Indicate?
|1.||Map showing Rio Grande/Río Bravo Basin, United States and Mexico, showing major streams and riverbed-sediment sampling sites|
|2.||Map showing surface geology of the Rio Grande/Río Bravo Basin|
|3.||Graphs showing concentrations of selected trace elements in riverbed sediments of the Rio Grande/Río Bravo, Pecos River, and Arroyo Colorado|
|4.||Graph showing concentrations of selected organic compounds in riverbed sediments of the Rio Grande/Río Bravo and Arroyo Colorado|
|1.||Spatial and temporal trends of trace elements and selected organic compounds in riverbed sediments in the Rio Grande/Río Bravo Basin|
|2.||Number of sites sampled, detections, and nondetections of organic compounds in the Rio Grande/Río Bravo Basin|
